Title: An improved means for separating the constituents of semiliquid bodies
IPC: B01D35/02
Filed: 1930-12-05
Abstract: 367,944. Straining liquids ; tipping- wagons. SOUTHALL, T. J., Melrose, Barneshall, and GUISE, C., Gables, Court Road, Malvern, both in Worcestershire. Dec. 5, 1930, No. 36681. [Class 46.] Apparatus for separating solids from liquids, particularly sand and gravel from water, comprises a wedge - shaped container rotatably mounted and divided by a vertical perforated plate or plates into main and secondary compartments so that when a mixture is supplied to the main compartment the solid matter is retained while the liquid passes into the secondary compartment or compartments and is discharged therefrom. A tipping- wagon a, Fig. 1, mounted on trunnions a<1> is fitted with perforated plates b. Solid matter is retained in the central compartment e while liquid passes through the end compartments c to outlets d. Figs. 3 and 4 show in longitudinal and transverse section a container i, divided into longitudinal wedge-shaped compartments j and mounted on a shaft k, so that it can be rotated mechanically or manually by worm gearing. Small end compartments r are partitioned from the compartments by perforated plates o. Liquid passes away from solid matter deposited in the uppermost compartment into the corresponding compartments r and is discharged through outlets s to troughs u.

Abstract: 368,377. Combined cigarette &c. cases and lighters. KROPMAN, S. M., Crossways, Leicester Road, Broughton Park, Manchester. Dec. 5, 1930, No. 36688. [Class 18.] A cigarette &c. case comprises two separate compartments 7, 8 for a friction lighter 9 and cigarettes &c. respectively, and the compartment 7 is provided with a separate hinged lid 10 which forms part of the case and is released when the cover to the compartment 8 is closed, the opening of the lid 10 allowing a spring- actuated cover, extinguisher, or shield 9a on the lighter to fly up and generate a spark. The lid 10 may be pushed upwards by a spring of its own or by the spring in the shield 9a. A hooked extension 14 on the lid 10 is normally engaged by a spring-pressed hook 16 pivoted on the lighter, but the lid 10 springs open when the lower end of the hook 16 is pressed towards the lighter by an arm 19 pivoted on the hinge of the cover 12 to the compartment 8 ; this arm being pushed against, and sliding past, the end of the hook by the cover 12 as it closes. When the cover 12 is opened the lid 10 is not affected as a spring on the hinge of the arm 19 causes that arm to ride outwards past the lower end of the hook 16. Instead of a pivoted catch 16, a spring catch on the side of the lighter may be employed, this catch being pushed in when the cover 12 is closed. The lighter is detachable from its compartment. According to the Provisional Specification the cover to the lighter takes the place of the lid 10 ; and in this Specification, alternative methods of securing the lighter cover are described.

Title: Improvements in or relating to devices for raking together crops lying on the ground
IPC: A01D78/16

Abstract: 1,010,117. Haymaking machines. C. VAN DER LELY N.V. Sept. 27, 1962 [Sept. 28, 1961], No. 36765/62. Heading AlF. In a haymaking machine of the type having a series of parallel rake-wheels 11 mounted on supports 12 and positively driven, the supports are mounted on the frame 1 of the machine in such a way that the supports and the rake-wheels may be pivoted about a horizontal axis from a side-delivery position, wherein the rakewheels are vertical, to a tedding position, where they are oblique to the ground. The main frame is of inverted-U shape, adjustable swivel-wheels 2 being mounted upon the downwardly-extending limbs of the frame. A main beam 8 is mounted in slots 7 in the frame-limbs so as to be adjustable vertically and also rotatable about its axis, by means of a crank 10; nuts 9 clamp the beam in any adjusted position. Shafts 12, journalled in the frame carry rake-wheels 11 at one end and driving sprockets 13, 14 at the other; the sprockets are all connected by chains 11 to a gearbox 20 and thence by a telescopic shaft 27 to a gearbox 23, on the frame, which is driven from the tractor power take-off. The gearbox 20 has two input-shafts 21, 22, diametrically opposed, for alternate use when the main beam is rotated through 180 degrees. An arched member 3 is pivoted, at 5, to the frame 1 and terminates in a third swivelwheel 4, a drawbar 6 being mounted near this wheel. When the device is drawn in the direction alpha (Fig. 1) it operates as a sidedelivery rake discharging to the right; traction in the direction b, with the member 3 swung into the position 3<1> and the main beam 8 rotated through 180 degrees so that the rake-wheels occupy dotted positions 11<11>, converts the device for side-delivery to the left. Rotation of the main beam through 90 degrees so that the rake-wheels are slightly inclined to the ground (11<1>, Fig. 2) converts the device into a tedder. In a modification (not shown) the device is mounted on tractor hitch-links and has no ground-wheels.

In a machine in which a tool, e.g. a welding or cutting torch, is moved in a circular path around a non-rotatable workpiece, the tool is mounted on a C-shaped driven member straddling the workpiece and rotated by an endless chain engaging a substantial part of the periphery of the driven member, and an arcuate guide is provided to support the chain when it spans the open portion of the driven member. A portable machine for butt welding pipes 20, 22 consists of a U-shaped frame 30 fitting over the pipe 20 and having a hinged clamp 110 locked by a toggle linkage 116. A second clamp 32 is connected to the frame by a bridge 34 and the machine may have supporting legs. The C-shaped driven member 64 is rotatably held in a C-shaped bearing 66 fixed to the frame 30. One side of a double width chain 58 passes over the toothed periphery of the driven member 64, idler wheels 54, 56 and a sprocket 52 driven by a motor 28 while the other side engages the arcuate guide in the form of a ridge 78 on the bearing 66. The welding torch 26 is adjustably mounted on a bracket 84 rigid with a slide 88 spring-loaded towards the pipe 20 and carrying a roller 96 engaging the pipe 20. The slide 88 is supported in a housing 68 attached to the driven member 64. Members 100 secured to the chain 58 actuate switches 106, 108 for use in starting, stopping, reversing the direction of travel or varying the speed of travel. Welding may be effected in one revolution with overlap, in two downward half revolutions or where a consumable electrode or filler rod is used, a root bead may be deposited in one direction and the joint be filled by oscillating the torch as it is moved in the reverse direction.

A synthetic sponge containing a charge of detergent or other suitable substance is made by placing a plurality of such charges in a pasty or solid state in the body of a block of spongy plastics material foam and then cutting up the block to form individual sponges each of which contains a charge of the substance. The substance may be a perfume, a therapeutic agent, a deodoriser, a cleaning agent or a stain remover. Preferred spongy material is polyurethane foam. The charges may be emplaced by injecting the substance in a pasty form from a plurality of injection needles driven to a suitable depth into a pre-formed block of the plastics material foam. Alternatively, a series of charges in solid form are mounted on rods in the mould in which the plastics foam is to be expanded, so that, when the foam fills the mould and sets, the charges are embedded therein; the rods are then withdrawn leaving the charges within the sponge block. Reference has been directed by the Comptroller to Specification 848, 413.
